Chevy 235...valve stem seals?

I have a 55 Chevy truck that I have worked on, on and off, for 20 years. The 235 block is not original and was rebuilt by me 20 years ago...however I'd be surprized if there is even 10,000 on the block.

The head is from the original engine..It had a crack and was "stitched" (I believe thats the term) I'm not certain if I had any other head work done to this.

I'm visibly burning oil...and suspect the Valve stem seals. I haven't done a leak down test yet but I will. In the meantime I pulled the valve cover to look at the seals. I don't see anything rubber at all between the valve guide and the top of the spring..no groove with an O ring or umbrella...If I had them that's where they would be right? I have anothere head to rebuild(It's where I lived 7 years ago...it's still in the basement) but in the meantime..for education sake..am I missing something?

Thanks,

Keith
